About this study

Official title: Minimally Invasive Molecular Approaches for the Diagnosis of Barrett's Esophagus and Esophageal Adenocarcinoma- R01 Aim 1a Renewal (SOS5C Trial)

This clinical trial studies how well minimally invasive approaches (an artificial intelligence [AI] powered risk tool, nurse navigation, and a sponge on a string [SOS] test) work in diagnosing patients with Barrett's esophagus (BE) and esophageal cancer. Esophageal cancer has a poor 5-year survival rate when diagnosed after onset of symptoms. While rising, incidence of esophageal cancer remains too low to screen the entire population. BE is a condition in which the cells lining the lower part of the esophagus have changed or been replaced with abnormal cells that could lead to esophageal cancer. Currently, patients are screened for BE based on certain risk factors (reflux, age > 50 years, White race, family history of esophageal cancer, obesity, male sex, and smoking), followed by endoscopies and surgery for treatment. These standard procedures may result in under-recognition of BE risk due to inaccurate and difficult to use risk assessment tools, high cost, invasiveness, low access to endoscopy, and sub-optimal recognition of abnormal cells during routing endoscopy. An AI powered risk tool that integrates symptoms, health history, and laboratory values from electronic health record data may more accurately assess BE and esophageal cancer risk that manual assessment. The BE-SOS screening test combines a swallowable cell collection device with assessment of DNA, which may more accurately diagnose abnormal cells. Nurse navigation involves trained personnel assisting individuals through the screening process and completing the follow-up diagnostic test if the screening test is positive. Navigators address cultural, social, access, and logistical barriers to screening. Nurse navigation may increase completion rates of diagnostic procedures following a positive screening test. These minimally invasive approaches may enable higher rates of BE screening than currently being accomplished.

Arm 1 (T1 SOC, T2-T4 Intervention)ExperimentalFamily Medicine Care Teams in Cluster A provide SOC procedures during T1 consisting of the following: 1) Care teams manually assess BE risk for patients, and patients meeting ACG criteria are recommended to undergo BE screening with BE-SOS test followed by endoscopy (only if BE-SOS positive). Family Medicine Care Teams in Cluster A then provide intervention procedures during T2, T3, and T4 consisting of the following: 1) Care teams utilize RN navigators that assist in using the AI powered BE Risk Tool to assess patients' BE risk; 2) Patients with AI powered BE Risk Tool high risk result undergo BE-SOS test with RN navigator assistance; 3) Patients with positive BE-SOS test results then undergo endoscopy with RN navigator facilitation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of completed Barrett's esophagus (BE) screening

    Assessed as the proportion of patients who complete BE screening. This is determined as the number of patients who complete a sponge on a string (SOS) BE screening test or endoscopy screen, divided by the number of screen eligible patients in each group.

    Measured: Baseline (completion of endoscopy)

  2. Negative predictive value of the AI powered BE Risk Tool (Aim 1b)

    A randomly selected sample of patients (N=50) with a negative BE risk tool score will undergo a research upper endoscopy to confirm the high estimated negative predicted value of the BE risk tool.

    Measured: Baseline (completion of endoscopy)

Secondary outcomes (5)
  1. BE screening ordered (completed + not completed)

    Assessed as the proportion of patients who complete BE screening (SOS BE screen test or endoscopy) for patients where BE screening has been ordered.

    Measured: Baseline (completion of endoscopy)

  2. Successful completion of the SOS BE screen test

    Assessed as the number that had successful test completion (a test result was received) divided by the number of patients where a BE-SOS test/endoscopy order was placed

    Measured: Baseline (completion of endoscopy)

  3. Completion of diagnostic endoscopy following a positive SOS BE screen test

    Assessed as the proportion of patients who complete diagnostic endoscopy following a positive BE-SOS test.

    Measured: Baseline (completion of endoscopy)

  4. Rates of BE [with or without dysplasia/esophageal adenocarcinoma (EAC)]

    The proportion of patients with BE/EAC diagnoses will be determined as the number with a BE/EAC diagnosis divided by the number of patients who underwent BE-SOS or endoscopy.

    Measured: Baseline (completion of endoscopy)

  5. Patients flagged for screening by the BE risk tool in the intervention clusters who also meet American College of Gastroenterology (ACG) BE screening guidelines

    The proportion of screen eligible patients in the intervention arm who meet ACG screening criteria will be determined as the number meeting screening criteria divided by the number in the group.

    Measured: Baseline (completion of endoscopy)
